Attributes

Attribute

Default

Description

session-file-name

none; state is not preserved across restarts

(optional) Specifies the absolute or relative path to the directory
in which the session state is preserved between application restarts,
if preserving the state is possible. A relative path is relative to
the temporary directory for this web application. Applicable to the web container only if the persistence-type attribute of the web-container-availability element is memory.

reap-interval-in-seconds

60

(optional) Specifies the time between checks for expired sessions.

If the persistence-frequency attribute of
the web-container-availability element
is set to time-based, active sessions are stored
at this interval.

Set this value lower than the frequency at which session data
changes. For example, this value should be as low as possible (1 second) for a hit counter servlet on a frequently accessed
web site, or you could lose the last few hits each time you restart
the server.

max-sessions

-1

(optional) Specifies the maximum number of sessions that can
be in cache, or -1 for no limit. After this, an
attempt to create a new session causes an IllegalStateException to
be thrown.
